Petty cash or commonly referred to as petty cash is a number of funds that are specifically designated as expenses that are relatively small in number and nature. Petty cash is usually used to finance the company's operations or other matters related to the activities carried out by the company. The establishment of a petty cash fund is part of the company's internal control principles. To establish a petty cash fund, a good arrangement in petty cash management is needed, one of which is by making a petty cash fund application form and proof of receipt of petty cash funds. This form is submitted if the petty cash balance is running low or even the balance has run out. The main purpose of using the petty cash fund application form and the petty cash fund receipt form is to carry out internal control over the company's cash.
